Filed: 1993-12-14
Abstract: PURPOSE:To obtain a solar sensor having the less number of solar battery cells by detecting the direction of the sun in one direction from the outputs of the first and the second solar battery cells and detecting the direction of the sun in the other direction from the outputs of the second and the third solar battery cells. CONSTITUTION:When the solar beams deflect to the positive direction from the position of the original point of an X-axis 16, the light receiving area of a solar battery cell 13 increases oven the light receiving area of a solar battery cell 14. Accordingly, the output of the solar battery cell 13 becomes larger. Further, when the solar beams deflect to the negative direction of the X-axis 16, the reverse effect is obtained. Utilizing such the relation, the direction of the solar beam on the X-axis 16 is detected. Further, when the solar beams deflect to the positive direction from the original point position of a Y-axis 17, the light receiving area of the solar battery cell 15 becomes larger than the light receiving area of the solar battery cell 14, and the output of a solar battery cell 15 becomes larger. Because of such the relation, the direction of the solar beam on the Y-axis 17 is detected. With such the constitution, the direction to the sun can be detected by three pieces of solar battery cells.

Title: Zooming system
Inventor: OTAKE YOSHITOMO
IPC: G02B7/34
Filed: 1986-12-27
Abstract: PURPOSE:To attain sure focusing even at the time of zooming by controlling the moving speed of a movable lens in its optical axis direction so that an image forming point based upon a change in a focal distance is changed approximately linearly to zooming time. CONSTITUTION:An image forming point A is changed approximately linearly to the rotationed angle of a cylindrical cam 7 by specifying the shape of a cam groove 8 in the relation between a distance (a) based upon the movement of a movable concave lens L due to the cam groove 8 and the rotational angle thetaof the cam 7. Since a power zooming motor 9 is rotated at a constant speed, the rotational angle theta of the cam 7 is changed at a constant speed and a change at the image forming point A is approxilmately linear to time. Thereby, the change of the image forming point A about the zooming time can be approximately linearly set up so as to pass from a point P1 to a point P2, and when the cam 7 is rotated at the constant speed, the change at the image forming point A of a zoom lens can be set up approximately linearly to the zooming time. Consequently, accurate focusing always following the changed on the image forming point at the time of zooming can be attained.

Title: Manufacture for stamper and optical master disk
Inventor: TSUCHIYA MASAO
IPC: B29L11/00
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To improve quality reliability of a stamper. SOLUTION: A base body having a nearly equal thickness and a nearly equal refractive index to an optical disk is formed, on one face of which is formed a projecting/recessed pattern of a photoresist 22 showing a nearly equal refractive index to the optical disk. A conductive film layer 23 and an electric plating film are sequentially formed on the projecting/recessed pattern. After the conductive film layer 23 is formed and/or the electric plating film is formed, then, a laser light is projected on the projecting/recessed pattern from the other face of the base body. Since the projecting/recessed pattern is evaluated in this manner, it is surely prevented that a nonconforming pattern is judged as within specifications.  Since the base body having approximately the same thickness and refractive index as the optical disk and the projecting/recessed pattern of the photoresist formed on one face of the base body and having approximately the same refractive index as the optical disk are arranged, the projecting/ recessed pattern can be evaluated almost under the same condition as the optical disk.
